Tracey Campbell Fitzpatrick (36) will be removed to her native Mayo as St Luke's Hospital in Kilkenny confirmed that a full review is now underway into the precise circumstances of the tragedy.

The mourners will be led at her Requiem Mass tomorrow by her heartbroken parents, James and Pauline Campbell, her husband, Bernard, her children, Jamie, Adam and Max, and her siblings, Amanda, Paula, Diane and Alan.

Mrs Fitzpatrick, who married in 2014, gave birth to a healthy baby boy in St Luke's Hospital on Easter Monday. The boy, her third son, was named Max.

However, shortly after the delivery, Mrs Fitzpatrick's condition suddenly began to deteriorate.

Medical staff became very concerned about the status of the young mother.

She was rushed to an ­operating theatre for treatment.

Sadly, she died before ­emergency surgery could begin.

"The staff and management of St Luke's Hospital are currently focused on supporting the family at this very sad time," a hospital spokesperson said.

"An internal review process has commenced, with a full investigation to follow."

The Kilkenny Coroner's Office has also been notified.

The full details of the hospital review will now be compiled for Coroner Tim Kiely.

A post mortem examination was carried out on Tuesday at St Luke's Hospital.

The hospital review could now take between two and three months to conclude.

Mrs Fitzpatrick had been living with her husband and children in Templepeter outside Nurney, Co Carlow.

Her husband and his family are from the Templepeter and Nurney area.

The Fitzpatricks were described by neighbours as lovely people who are very involved in the local community and sporting organisations.

Mr Fitzpatrick was too heartbroken to comment on the tragedy.

Hundreds extended their sympathies last night as Mrs Fitzpatrick lay in repose at her Carlow home.

The 36-year-old was from Shanvaghera, just outside Knock in Co Mayo.

A special Mass for Mrs Fitzpatrick will take place at 11am today at St Patrick's Church in Rathoe, Co Carlow.

Her remains will then be taken to her parents home in Mayo where she will remain in repose.

She will then be removed to St Ann's Church, Shanvaghera for 11am Requiem Mass on Friday with the burial taking place at nearby Knock cemetery.

Carlow neighbours said they were still trying to come to terms with the sheer scale of the tragedy.

"Everyone is heartbroken by it," explained one local woman who asked not to be named.

"It is terrible to think that while the whole country was taken up by the Easter Rising ceremonies on Monday three little children were losing a devoted mother."

"They are a lovely family and we are just so devastated for them."

Ireland records an average of two maternal deaths each year.

These are defined as the death of a mother during pregnancy or within 42 days of her pregnancy ending.
